Filed July 30, 1962, Ser. No. 213,396 1 Claim. (Cl. 30-368) This invention relates to an indexing tool for punching addressograph cards.

One of the objects of this invention is to provide an indexing tool which will punch out a clean opening in an addressograph card.

In punching out the openings in addressograph cards the problem exists of providing a clean opening, that is, an opening in which the circular edge is smooth and free of any ragged edges or ragged surfaces. This invention overcomes the problem by the use of a simple and inexpensive easily operated tool which punches out a clean circular opening.

Another object of this invention is to provide an indexing tool which will not bend the clips which hold the addressograph cards.

Other objects and advantages will become apparent as this description progresses.

In the drawings:

FIGURE 1 is a view showing the indexing tool and the addressograph plate and its support.

FIGURE 2 is a cross-sectional view taken on lines 22 of the indexing tool shown in FIGURE 1.

FIGURE 3 is a cross-sectional view taken on lines 3-3 of FIGURE 1.

FIGURE 4 is an enlarged view taken on the circle of v FIGURE 3, and

FIGURE 5 is a sectional view showing the indexing tool punching an addressograph card.

The addressograph plate, generally indicated at 10, is of conventional construction and includes a card 12 properly imprinted. The card 12 is supported on a holder plate 14 made of metal or the like. The holder plate 14 is provided with inwardly turned clips 16 which engage the card to retain it on the holder plate. As seen in FIGURE 1, two such cards are held on a holder plate 14. The holder plate is provided at its opposite sides with downwardly extending ribs 18. That portion of the holder plate over which the cards 12 extend is provided with a plurality of equally spaced circular openings 20 which are in vertical alinement with the numbers or designations on the printed card 12 to permit a circular opening to be punched in the card.

The plate holder 14 is supported on a base generally indicated at 22, having a bottom 24 and spaced upwardly extending sides 26 and spaced upwardly extending front and rear walls 28. The sides 26 are provided with channel-shaped recesses 30 at the top thereof to accommodate the ribs 18 on the holder plate 14, wherein the holder plate 14 is supported across the base spaced from the bottom, as shown in FIGURE 3.

Fixedly secured to the sides 26 of the base 22 and extending across the open top is a metal plate 32 having a plurality of spaced circular openings 34. The openings 20 in the holder plate 14 are of the same size and are similarly positioned as the openings 34 in the plate 32, so that when the holder plate with the cards attached are positioned on the base 22, as shown in FIGURES 1 and 2, the openings 20 in the holder plate 14 and the openings 34 in plate 32 will be in vertical alinement. The foregoing is conventional.

The indexing tool forming this invention is shown in FIGURES 1, 2 and 5 and is generally indicated at 36.

3,178,819 Patented Apr. 20, 1965 It comprises a tubular body or holder 38, the lower end of which is internally threaded at its inner end as at 40 to receive a cutting tool generally indicated at 42. The cutting tool includes an externally threaded plug 44 which continues forwardly to form a short annular stem 46 of reduced diameter to form a shoulder 48 between the plug and the stem. Continuing forwardly of the stem 46 is the pin portion 50 of a further reduced diameter, and a shoulder 51 is provided between the stem 46 and pin 50. The front end of the pin is shaped to form a saber point 52.

As shown, the cutting tool 42 has the threaded plug 44 in threaded engagement with the tubular body 38. A portion of the threaded plug extends beyond the inner end of the body 38 so that same may be secured to the nose portion generally indicated at 54. The nose portion 54 has a tapering front 56 and is internally threaded as at 60 to engage the lower threads of the plug 44 to secure the nose to the !body 38 and to the cutting tool 42.

A slidable sleeve 62 having a flange 64 at its upper end is positioned in the nose 54 so that a portion of the sleeve extends outwardly of the tip of the nose and with the flange 64 within the nose. A coil spring 66 is positioned inside the nose to surround the stem 46 and a portion of the pin 50 of the cutting tool 42. The spring 66 has one end resting on the flange 64 of the sleeve and the opposite end against the shoulder 48 to normally apply a pressure against the sleeve 62 and urge it outwardly to its fullest forward position, as shown in FIG- URE 2, wherein the flange 64 of the sleeve rests on the shoulder 58 of the nose. With the sleeve fully extended forwardly, only the tip of the saber point 52 is exposed, as shown in FIGURE 2.

To perform the punching operation of the addressograph card 12, the operation is performed as shown in FIGURE 5. The saber point 52 is positioned on the card 12 and the body or holder 38 is pressed downward. The saber point punctures the card and as it enters the punctured opening of the card it pushes the adjacent card material 12a downward into the opening 20 of the holder plate 14, as well as the alined opening 34 in the plate 32. The punctured card material at this stage is jagged and no clean circular opening has been formed. The exposed end of the sleeve 62 would be abutting against the top of the card 12 and the parts of the indexing tool would be as shown in FIGURE 2.

To complete the operation, the tool is pushed manually downward causing the sleeve 62 to move inwardly in the nose 54 until it abuts against the shoulder 51 which is the limit of the sleeves inward movement. The saiber end 52 and the portion of the annular pin 56 adjacent the saber end enters the card opening, as shown in FIGURE 5, to complete the cutting operation wherein the card material 12a is pushed down and through the alined openings 2t and 34 to produce a clean circular opening in the card 12. The exposed end of the sleeve 62 continually abuts against the top of the card 12 during this operation.

In withdrawing the saber end 52 from the punched card, the exposed end or tip of the sleeve 62 will continue to rest or abut against the card, as the spring 66 will urge the sleeve outwardly of the nose 54 as the manual pressure on the holder 38 is released. This causes the saber end to move upwardly out of the punched hole while maintaining the tip end of the sleeve against the card. This prevents the card from moving up with the pull out or withdrawal of the saber end.

By virtue of this construction it will be seen, particularly in FIGURE 5, that when the sleeve 62 has withdrawn to its full limits in the nose 54 that there is a space 70 between the tip of the nose 54 and the tip of the sleeve. This permits this unit to punch the addressograph card adjacent the clips 16 without bending the clips 16.

threaded, a cutting tool having an externally threaded plug in threaded engagement with said body to maintain said cutting tool in a fixed adjusted position relative to said body, said threaded plug and cutting tool being axially adjustable with respect to said body, a cutting edge on said cutting tool, a nose having an internally threaded end in engagement with the externally threaded plug on said 7 to said body, said plug serving as the only means for connecting said body to said nose, a sleeve sl-idably mounted in said nose, a coil spring in said nose biased against said sleeve to normally urge the sleeve outwardly of said cutting tool to secure said nose to said cutting tool and p a nose to cover a portion of the cutting edge of said cutting tool, the outer end ofsaid sleeve adapted to engage.

the addressograph card andsaid sleeve adapted to recede inwardly in said nose when said tool is depressed, stop means on said cutting tool engaged by said sleeve to arrest the inward movement of said sleeve.
